This video demonstrates in vitro stimulation of macrophage extracellular traps (METs) in human monocyte-derive macrophages using different inflammatory stimuli such as TNF-alpha, PMA, and HOCL. The video also demonstrates the method of SYTOX dye staining of METs for visualization.
1. Polarization of HMDM
2. Stimulation of HMDM to induce MET Release
3. Visualization of MET in Live Cell Culture
